yeah, exactly. For me was really surprising we can't fix her and the end (and trust me completing the game with patch 0 was really painful), but the worst thing was why we can't fix her. The reason is "nobody knows", Dammon is silent, Gondians are silent which is really sad. The most obvious ways to fix her are not closed. You should give Dammon enriched infernal ore and there should be cutscene with failed fix attempt, something similar with Gondians and theirs engines. Then you can accept the most idiotic sentence in whole game "We did everything we can to save Karlach". And then I'm totally fine with sad ending, sometimes everything is not a happy ending.
